    May as well keep going... decided it would be easiest to do a nice job if I remove the entire plenum.

    Also gives me good access to under the dash! Will help to sort the tight squeeze with demister duct and dash instruments and wiring.

    Do it once, do it right. Nice work.

    Its great being able to access the back of the dash so easily. The demister ducting shouldn't need huge modifications, the driver side inlet clashes with the mounting for the new instrument cluster but since the ashtray is going away there's plenty of room to move it over a little.

    Will also need to squeeze it up a bit on the driver side but still plenty of volume left. After some trimming it now fits around the instrument cradle, and I think it should be possible to assemble everything from under the dash once the plenum goes back in.

    Made a few tweaks to the VN under-bonnet relay/fuse holder, bent the tabs for the main fuse/breaker box over to the opposite side and trimmed off the original mounting pieces. Made a couple of standoffs for mounting it along the driver side edge in the Torana engine bay.

    Installed and showing where the wiring enters from under the guard.

    Still have plenty of work to tidy up wiring but everything here is connected, should all but disappear once wrapped but still leaves all the relays and fuses easily accessible and exactly as per VN/VP wiring for easy maintenance.

    The VN/VP looms have earth wiring for almost everything instead of having to rely on sheet metal screws and the like, so may as well take advantage of it. Front indicator housings are not big enough to take the later model bulb holder complete, so I decided to add provision for the earth wire.

    Started by milling a 3mm slot in the housing for the wire itself (top of photo)

    This goes through the back but stays inside the rubber boot area and doesn't impede on the bulb or contacts

    Soldered the end to the back of the earth contact

    Holden was good enough to use a rubber boot designed for two wires so just had to make the second hole. Dug around in the wiring bin and found a suitable plug to match the standard one on the Commodore loom, also turns out this uses the exact same style connectors as the original so the blue wire just had to be swapped from the single-pin to the two-pin. Add the new earth wire and ready to go.

    Slowly working away on the wiring in general, front end is starting to take shape. Torana headlight connectors are in place and everything along the top here is done, the wires hanging down in front of the wheel go to the engine and main power feed from battery and will be clamped underneath (in front of the wheel well) with protection.

    Dismantled the Torana light switch, replaced the 45-year-old grease, and confirmed that the headlight and park/tail light circuits are completely separate. This allows tying directly into the VN loom which has relays for the headlights and switches the ground rather than positive (but still switches the positive for park/tail lights). So that made it simple, only change was to cut the dimmer output into the positive side of the instrument illumination (VN dimmer works on the ground, but the Torana dimmer feeds from the positive park/tail circuit). The dome light output is ground for both so no issues there.

    Also swapped over the ignition switch connector, added a larger wire for the crank feed (yellow) and tied it to the normal ignition feed (pink) so we have power to everything required during cranking.

    Slowly working away at the wiring stuff while I have the under-dash area exposed. Going to use a combination stalk (HZ/UC/early Commodore) which makes wiring it to the VN loom easy, and no issues with current capacity since all the big stuff uses relays.

    Also had a closer look at some indicator switch mechanisms to see whether I could add hazard lights - the early Commodore switch has this built in to the indicator switch, but the Torana switch also has a trick in that it allows to override the rear indicators for reverse lights. Turns out they are exactly the same, just with different parts used - Commodore on left, Torana on right:

    The three wires at right are the rear indicators (Commodore just deleted these and tied front and rear together), the brown wire is the input from the hazard flasher (uses a separate flasher so it can be battery instead of ignition only).

    So I built one with all the wires:

    The hazard switch mechanism is just part of the wire cover plate, and joins all the required circuits together. Works a treat according to the multimeter.
